## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Output 1 | output | Op-amp 1 output. Rail-to-rail output stage swings within ~100 mV of VDD/VCC; short-circuit protected. |
| 2 | Inverting input 1 | input | Op-amp 1 inverting input (IN−). Common-mode range VDD+1.15 V to VCC−1.15 V; do not exceed VDD−0.3 V or VCC+0.3 V. |
| 3 | Non-inverting input 1 | input | Op-amp 1 non-inverting input (IN+). Same input constraints as IN−. |
| 4 | VCC | power_in | Positive supply. Operating range 2.7 V to 10 V single-supply (or up to ±5 V split-supply). Absolute max 12 V. |
| 5 | Non-inverting input 2 | input | Op-amp 2 non-inverting input (IN+). |
| 6 | Inverting input 2 | input | Op-amp 2 inverting input (IN−). |
| 7 | Output 2 | output | Op-amp 2 output. Rail-to-rail; short-circuit protected. |
| 8 | Output 3 | output | Op-amp 3 output. Rail-to-rail; short-circuit protected. |
| 9 | Inverting input 3 | input | Op-amp 3 inverting input (IN−). |
| 10 | Non-inverting input 3 | input | Op-amp 3 non-inverting input (IN+). |
| 11 | VDD | power_in | Negative supply / ground reference. Tie to GND for single-supply operation, or to the negative rail for split-supply operation. |
| 12 | Non-inverting input 4 | input | Op-amp 4 non-inverting input (IN+). |
| 13 | Inverting input 4 | input | Op-amp 4 inverting input (IN−). |
| 14 | Output 4 | output | Op-amp 4 output. Rail-to-rail; short-circuit protected. |
